I wasn't sure how to answer your poll.
If you meant ANY kind of pb then the answer is 2. I had an RE where I "found" a Christmas Pet Paint Brush. I also had an RE where I "found" a White PetPet Paint Brush.
I have won 1 Tyrannian Pet Paint Brush from the Wheel of Monotony. I would also like to let you know how much I appreciate your site and your polls. They are so much more revealing and informative than are the one on Neopets. Thank you.
